Laboratory Acoustics / Noise Control

The activities of the Empa Laboratory for Acoustics/Noise Control are based on the fact that noise is one of the major environmental problems, and that soundscapes in buildings and in the built environment have a substantial impact on health, wellbeing and performance.

It is therefore our mission to investigate and understand the mechanisms of sound generation, transmission and radiation, as well as the effects of noise. On this basis we develop low noise technologies, models and tools together with our industrial partners. Further we offer high quality services and we support the governmental agencies with science-based solutions for legal noise abatement.
Our research focuses on the following two topics:
  • Environmental Acoustics – Impact Driven Noise Control
    In Environmental Acoustics we develop models and tools to calculate noise exposure. Based on auralizations and psycho-acoustic experiments we study the human perception of sound and the spontaneous reaction to noise. This knowledge allows us to optimize sound sources and design measures on the propagation path to minimize noise impact on humans.
     
  • Materials & Systems – Acoustics in Structures and Complex Materials
    Top-notch modelling and prediction in acoustics and material dynamics complements our experimental excellence for an application driven environment.
